Synthesis of zeolite-magadiite composites＂ Effects of co-solvent and aluminum source

The one-pot synthesis of ZSM-5-magadiite, ZSM-23-magadiite, and ZSM-5-ZSM-23-magadiite using isopropylamine and 2-propanol as an organic structure-directing agent and co-solvent, respectively, was studied. Zeolite mixtures were prepared by adding 2-propanol （0 to 10wt%） to the reaction solu- tion. T...

Description
Summary:The one-pot synthesis of ZSM-5-magadiite, ZSM-23-magadiite, and ZSM-5-ZSM-23-magadiite using isopropylamine and 2-propanol as an organic structure-directing agent and co-solvent, respectively, was studied. Zeolite mixtures were prepared by adding 2-propanol （0 to 10wt%） to the reaction solu- tion. The intergrowth of composites was observed when 2-propanol was introduced as a co-solvent into the reaction mixture. Synthesized samples were characterized by X-ray diffraction, field-emission scan- ning electron microscopy, energy-dispersive X-ray spectroscopy, and thermogravimetric analysis. The results revealed that the amount of 2-propanol and source of aluminum influenced the nature of the zeolite-magadiite composites formed.
